IOCs

binary

  • identical for all hadcons

startup cmd file

st.cmd
sources st_${HOSTNAME}.cmd for host specific database

database

  • makes extensive use of template/substition functionality of EPICS
  • mainly connects via streamDev protocol functions to the API of Hadcon's micro controler
    • using as asyn port hadcon's internal serial interface device /dev/ttyS1 connected to the μC
  • takes care of non-conflicting access to the μC
    • hadcon_global_scan.template, which calls task specific "globals" initiating the read/write action
      • hadcon_atmel_adc_global.template
    • or special tasks:
      • RPC gas system monitor:
        • hadcon_global_scan_rpc_gas_system.template
    • ...
  • other global, singular to the host, templates/db
    • hadcon_global.db
    • hadcon_debug_global.db
    • hadcon_show_global.db
